WARNING:
This information is intended
for use by individuals possessing adequate backgrounds
of electrical and mechanical experience. Any attempt to
repair a central air conditioning product may result in
personal injury and or property damage. The manufac-
turer or seller cannot be responsible for the interpreta-
tion of this information, nor can it assume any liability in
connection with its use.
The following instructions cover 2A6H3 Heat Pump Units.
NOTE: TRANE HAS ALWAYS RECOMMENDED INSTALL-
ING TRANE APPROVED MATCHED INDOOR AND OUT-
DOOR SYSTEMS.
THE BENEFITS OF INSTALLING APPROVED INDOOR
AND OUTDOOR SPLIT SYSTEMS ARE MAXIMUM EFFI-
CIENCY, OPTIMUM PERFORMANCE AND THE BEST OVER-
ALL SYSTEM RELIABILITY.
Check for transportation damage after unit is uncrated. Report
promptly, to the carrier, any damage found to the unit.
To determine the electrical power requirements of the unit, refer
to the nameplate of the unit. The electrical power available must
agree with that listed on the nameplate.
The Heat Pump has been designed and manufactured to with-
stand and operate in severe winter conditions. However, there
are precautionary steps which should be taken at the time of
installation which will help assure the efficient operation of the
unit.
It is recommended that these precautions be taken
for units being installed in areas where snow accumula-
tion and prolonged below freezing temperatures occur.
1.
Units should be elevated 3 to 12 inches above the pad or
rooftop, depending on local weather. This additional height will
allow better drainage of snow and ice (melted during defrost cycle)
prior to its refreezing.
This should prevent a buildup of ice around
the unit which occurs when unit is not elevated.
Insure that drain
holes in unit base pan are not obstructed preventing drain-
ing of defrost water.
2. If possible, avoid locations that are likely to accumulate snow
drifts. If not possible, a snow drift barrier should be installed
around the unit to prevent a buildup of snow on the sides of the unit
and should be of sufficient distance from the unit to prevent
restriction of airflow to and from the unit. Also allow for proper
maintenance space. The barrier should be constructed of mate-
rials which will blend in with the building design.
3. Avoid locating the unit where condensation and freezing of
defrost vapor may annoy the customer. For instance, installing
the unit under a bedroom, kitchen, or picture window may be
annoying to the customer since condensate and fog will occur
during the defrost cycle.
4. Avoid locating the unit under the eaves or other overhead
structures as sizeable icicles may form and the unit may be
damaged by these falling icicles.
